Update No. 2:Back in stock at Ice Monkey, at least for now! Which is good, because the Amazon one is now out of stock from that seller, and now going for around $9 from another one.

You'll note that the product page calls this a 4-in-1 cable, but that's not technically accurate: It's a USB cable that splits off into three plugs. (In an ideal world, it would indeed have a fourth: miniUSB, although fewer and fewer devices rely on that kind of port.)

The cable (which measures a travel-bag-friendly 1 foot in length) lets you sync and/or charge any compatible device. According to the product description, it can charge three devices simultaneously, though I think if you split a USB port's power output three ways (or even two), you wouldn't get sufficient juice for any of them. At the very least, charging would take significantly longer.

In any case, I think this is more about the convenience of packing one cable instead of three. And to my thinking, that's a convenience well worth 7 bucks out the door.

Bonus deal: Every car should have Bluetooth. If yours doesn't, consider an adapter. Like this one: Accessory Genie has the GoGroove SmartMini Bluetooth car adapter for $24.99 shipped when you use coupon code SMARTAUX at checkout. (That's a CNET exclusive, cheeps!) This dash-mountable unit offers both hands-free calling and audio streaming, the only caveat being that your car stereo needs an accessible auxiliary input (for connecting the 3.5mm audio plug).

Bonus deal No. 2: Calling all parents! For a limited time, Amazon is offering 25 children's e-books for $2 each. You'll need a Kindle to read them, preferably a color one. I'm thinking you can't go wrong with "Pirates, Ho!" and "Baseball Hour," though let us not overlook the simple joys of "Eliza's Kindergarten Surprise."
